[PATCH 7/7] gcov: architecture specific compile flag adjustments

[PATCH 7/7] gcov: architecture specific compile flag adjustments

[Peter Oberparleiter]

From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>

Exclude code from profiling which is not linked to the main kernel or
which is running in a context not compatible with the assumptions made
by gcc's profiling code.
